(4) ‘Diesel engine’ means a compression ignition engine.

(5) ‘Environmental Mitigation Trust Agreement’ means the fully executed Environmental Mitigation Trust Agreement for State Beneficiaries effective October 2, 2017, and issued pursuant to Paragraph 17 of the Volkswagen ‘Clean Diesel’ Marketing, Sales Practices and Products Liability Litigation partial consent decree dated October 25, 2016.

(6) ‘Equivalent equipment’ means a piece of equipment that performs the same function and has the equivalent horsepower to a piece of equipment subject to a replacement.

(7) ‘Equivalent motor vehicle’ means a motor vehicle that performs the same function and is in the same weight class as a motor vehicle subject to a replacement.

(8) ‘Gross vehicle weight rating’ means the value specified by the manufacturer as the maximum loaded weight of a single or a combination vehicle.

(9) ‘Heavy-duty truck’ means a motor vehicle or combination of vehicles operated as a unit that has a gross vehicle weight rating that is greater than 26,000 pounds.

(10) ‘Incremental cost’ means the cost of a qualifying repower or retrofit less a baseline cost that would otherwise be incurred in the normal course of business.

(11) ‘Medium-duty truck’ means a motor vehicle or combination of vehicles operated as a unit that has a gross vehicle weight rating that is greater than 14,000 pounds but less than or equal to 26,000 pounds.
